' v1916. serial No. 115,241.

To all whom it may concern:

. Be it known that I, HOWARD BARBnR, a

;don and State of Connecticut, have invented .a new and useful Improvement in Cutting and Folding Machines, of which the following is a specification.

The object of my invention is to provide certain improvements in cutting and folding machines whereby a plurality of superimposed narrow webs may be positively and accurately fed in absolute register through the sheet cutting mechanism to the folding mechanism, thereby permitting the sheet cutting and folding mechanisms to be run at a much higher speed than would otherwise .be possi'ble'were the webs not so positively and accurately fed.

My'invention more specifically comprises two pairs of positively driven coacting endless belts, the belts being located beyond the sides of the webs and-beyond the ends of'the coacting members of both the cutting and folding mechanisms, said belts having coacting bars which project inwardly from the belts in position to grasp between them the sides of the superimposed narrow webs, each pair ofsaid bars having an interlocked engagement.

A .practcal embodiment of my invention is represented in the accompanying drawings, in which,

Figure l'r'epresents the cutting and folding m'achinein side elevation.

Fig. 2 is a front view of the machine, and

Fig. 3 is a vertical section taken in the plane of the line A- A of Fig. 2, looking in the direction of the arrows.

I haveshown three sets of rolls 1, 2, 3, 4, 5, 6, arranged to superimpose six narrow webs.

The cutting mechanism includes a pair of coacting rotary cutters 7, 8, carried by the shafts 9, 10, mounted in the side frames of the machine. The folding mechanism in- 'cludes the male folding cylinder 11 and the female folding cylinder 12, carried by their respective shafts 13, 14, mounted in the side frames of the machine. The male folding cylinder 11 is shown as provided with two sets'of grippers 15, 16, and two sets of folding blades 17, 18. The female folding cylinder 12 is shown as provided with two sets cf folding jaws 19, 20, arranged to coact with the folding blades 17 and 18 respectively. V

The sheet delivery mechanism is herein shown as com-prising the endless tape carriers 21, 22, the guide 23, the rotary dropper 24, and the endless delivery carrier 25.

The cutting, folding and delivery mecha nisms may be of any well known or approved form.

28 pass around the drum 30, and the lower ends of said belts pass around the male foldin cylinder 11. The upper ends of the endless belts 27 and 29 pass around the drum 31, and the lower ends of said belts pass around sprocket wheels 32, 33. Each pair of coacting belts 26, 27 and 28, 29, is provided with pairs of coacting bars 34, 35 and 36, 37 ,respectively, which bars project inwardlv from the endless belts in position to grasp between them the sides of the superimposed narrow webs. These pairs of inwardly projecting bars are equally spaced apart along the endless belts and act as teeth for engaging recesses 38, 39, and .40, 41, in the peripheries of the drums 30, 31 respectively, and recesses 42, 43 and 44, 45 in the peripheries of the male folding cylinder 11. and sprocket wheels 32, 33 for insuring the positive driving of these belts.

Each pair of coacting inwardly projecting bars is also provided, the one member of a palr with a pin 46, and the other member with arecess for receiving the pin, to cause each pair of belts to have an interlocking driving engagement.

The sprocket wheel 32, 33,,are so arrangedwith respect to the male folding cylinder 11 that the pairs of endless belts will travel together from the drums 30,31, downwardly past the rotary cutters 7 8, to the folding cylinder 11, and from thence a short distance along the periphery of the folding cylinder before the belts are permitted to separate. This causes the grippers 15, 16, on themale folding cylinder 11 to have ample time to-close gently uponthe advance edge of the superimposed narrow webs" otherwise be possible."

Gearing 47, 4s, 49, 50, 51, 52, 53, 54, 55,

56, 57, 5s, 59, 60, 61, 62, 63, 64, 65, 66, provide means for driving the several mechanisms at the proper relative speeds. Guides 67, 68, are also provided for guiding the superimposed narrow webs from the cutting mechanism to the folding mechanism.

In operation, the narrow webs which pass over the rolls 1, 2, 3, 4 and 5, 6,-are superimposed and pass between the drums 30, 31, and are engagedat this point along their sides by the pairs of coacting bars projecting inwardly from the endless belts. These bars firmly grasp the superimposed Webs and the belts convey the Webs through the cutting mechanism, as hereinbefore described, where the advance edge of the webs, while still held in register by the bars, are engaged by either the set of grippers 15 or the set of grippers 16.

At about the time the grippers engage the webs, the cutting mechanism operates to sever the same and the sheets are then carried around the periphery of the cylinder 11, until the folding mechanism of the cylinders 11 and 12 co-acts to fold ofi-the sheets to the cylinder 12, from which cylinder 12 the folded sheets are delivered by the tape carriers 21, 22, guide 23,.and sheet dropper 24, on to the endless delivery carrier 25. Thus it will be seen that the superimposed narrow webs may be positively fed through the cutting mechanism to the folding mechanism in accurate registerand held in such register a suflicient time on the male cylinder to permit the easy operation of the grlppers. V V a This is a division of my Patent No. 1,263,837, dated April 23, 1918, for improve ments in cutting and folding machines, the claims in this present application being di rected tor the cutting mechanism and in the above named applica'tion'to the cutting and folding mechanism.

It is evident thatslight changesmay be resorted to in the form, construction and arrangement of the several parts without ,departing from the spirit andscope of my invention; and hence I 'donotwish to limit and described, but What I claimisi 1.
